105mm Pack Howitzer

The 105 mm light howitzer family traces its roots to interwar U.S. Army efforts to give field artillery a more mobile medium-caliber weapon. As airborne, mountain, and amphibious forces grew in importance, armies looked for guns that could be broken down, towed by light vehicles, or moved by aircraft. The resulting 105 mm systems became standard close-support weapons rather than siege artillery.

The design priorities were manageable crew workload, robust recoil control, and enough shell weight to support infantry over broken terrain. Compared with larger 155 mm weapons, a 105 mm howitzer could be moved faster and kept closer to maneuver units. The pack or light-howitzer concept accepted shorter range and smaller payload in exchange for mobility and steady fire support.

During World War II and later conflicts, 105 mm howitzers became familiar weapons in infantry divisions, airborne formations, and expeditionary forces. Many remained in postwar service or influenced later guns such as M101, M102, and M119. Their longevity shows why light artillery survived even as heavier, longer-range systems became dominant.
